Nutplate Drills

Nutplate drill countersinks are available in high speed steel or cobalt. The standard nutplate drill countersink is made of M7 high speed steel and is used for drilling aluminum and mild steel. The M42 cobalt drill is used for drilling hard steel or titanium. Nut plate drill countersinks are so named because they are used in nutplate pneumatic drill motors. These portable units incorporate nut plate drill jigs and the nutplate drill to drill consistent, properly drilled and counter sunk holes.

These machine specific drills are used with nut plate jigs to produce a high volume of holes that are to size, with consistent hole spacing and concentric between countersink and drilled hole. Nutplate drills easily start a hole in difficult to machine materials.
